Ubuntu VM102 8-vCPU 2K45 trial profile (2026-11-06)

Verified PVE config:
- VM102 cores: 8 vCPU
- memory: 6144 MB
- cpu: host
- vga: virtio-gl
- status: running after restart
- host physical CPU remains 4 cores / 8 logical CPUs reported by PVE host

Applied to box ticket desk-ubuntu-01 (192.168.1.72):
- resolution: 2560x1440
- fps: 45 (30 before)
- bitrate: 30000 kbps (20000 before)
- backup: /home/armbian/vdi-terminal/backups/ubuntu-8vcpu-45fps-20261106-172255-399874

This is a reversible A/B trial. It applies on the next Ubuntu connection. The VM still uses Sunshine KMS + libx264 software encoding; vCPU increase does not create hardware encoding. Acceptance must use actual stream FPS and drag/click P95 latency.
